Big Brother 3 (styled as "Big Brother 3: Project DNA") is the third installment of AR$ Big Brother franchise.
- Project DNA/Twin Twist: HouseGuest Stephanrooks145 has a twin, Loverofcats96. The two girls alternated shifts in the house, secretly switching places throughout the first 5 weeks. They survived the first five evictions playing as Steph, so both twins entered the game and played as individuals.
- Battle Of The Block: The Battle of the Block was a Major Twist this season. For the first five weeks, two HOHs were crowned; each HOH nominated two HouseGuests for eviction. The nominated HouseGuests battled for safety in the Battle of the Block competition where the winning pair was safe and the HOH who nominated them was dethroned.
- Jury Comebacks: For the first time in Big Brother history, the first four jurors competed against each another in a competition; the winner got to re-enter the house. lkaWong was able to return to the house at the beginning of Week 9 after beating Biscuit_junk, Revampedpants123, and xTheFutureMindx.
- Rewind Week: Another twist this season was the Rewind Button, which when pressed would stop the live eviction on air and rewind the entire week's competitions. The majority of the houseguests pressed it together not knowing what it was for.
